IWMWriterAdvanced2::SetInputSetting method (wmsdkidl.h)
[The feature associated with this page, Windows Media Format 11 SDK, is a legacy feature. It has been superseded by Source Reader and Sink Writer. Source Reader and Sink Writer have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use Source Reader and Sink Writer instead of Windows Media Format 11 SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The SetInputSetting method specifies a named setting for a particular input.
Syntax
HRESULT SetInputSetting(
[in] DWORD dwInputNum,
[in] LPCWSTR pszName,

[in] WORD cbLength
);
Parameters

The encoding settings set with this method are not persisted in the output file. If you want your custom player to have access to this information, you must save the values as custom metadata attributes in the file header.
